The detective saw one burglar peek out the front door and then retreat, police said. A second person went out the side door of the house with a handgun in his hand.

The detective said he saw the man start to raise the gun to point it at him, so he discharged his personal firearm, police said.

No one was hit. The man ran off through the back yard, police said.

"I heard three, three pops. Sounded like gunshots, and then I saw all these flashing lights, so I came out here. You know, cops running all over the place. You know, telling you, 'Get back in your house. Get back in your house,'" neighbor Dennis Dembinkski said.

A third person was found hiding in the detective's basement and was taken into custody.

A second suspect was arrested Tuesday morning. Police are looking for one more person.

Police said the detective is 44 year old with 16 years with the Milwaukee Police Department.

He's assigned to the Criminal Investigation Bureau and remains on full duty.

"It's terrifying for anybody to have their house burgled, anybody in any neighborhood. In this incidence, the burglars picked the wrong house, and I'm glad the officer's OK. I'm glad his family is OK," Flynn said.
